KornShell Plus is an operating environment, not an operating
system. It works like any other application running on your computer.
The common operating environment makes it possible to write shell
scripts and ensure portability between operating systems ranging from
the Amdahl UTS to the Windows NT.

The GNU-Win32 tools are ports of the popular GNU development
tools for Windows NT and 95. They run thanks to the Cygwin32 library
which provides the UNIX system calls and environment these programs
expect.

My favorite magazine in addition to being a good source of
small shell utilities and shell programs is
Sys Admin Magazine
, which can be found at
http://www.samag.com. The last time I
checked, the utilities and programs were located at
http://www.samag.com/code.html.
